UNITED STATES EMIL GRAF, OF NEW YORK, N. Y.

STBENGTH-TESTING AMUSEMEN T DEVICE.

Application filed January 7, 1922.

To (all whom it may concern:

Be it known that I, EMIL GRAF, a citizen of the Republic of Switzerland, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Strength-Testing Amusement Devices, of which the following is a specification.

One of the objects of this invention is to provide a strength testing amusement device which will be coin controlled and to a certain extent automatic in its operation whereby it will not require the services of an operator or attendant.

Another object is to provide in a device of this character an indicating member movable against the force of gravity along a graduated scale to indicate the force of a blow struck by the fist against a suitable padded member.

A further object is to provide a means for returning a coin to the user of the machine when a blow exceeding a certain force has been struck.

With these and such further objects in View as will be apparent as the description proceeds the invention consists in the following construction, combination and arrangement of parts hereinafter disclosed in the specification, reference being had to the accompanying drawings forming a part hereof and wherein a preferred embodiment of the invention is shown, though it is to be understood that such changes, variations and modifications as may fall within the scope of the claims hereinafter appended are within the purview of my invention.

In the drawings Fig. 1 is a vertical sectional view taken on line 1-1 of Fig. 7.

Fig. 2 is a detail section on the line 22 of Fig. 1.

Fig. 3 is a detail section on the line 3-3 of Fig. 1.

Fig. 4c is an enlarged detail section on the line 1-4 of Fig. 1.

Fig. 5 is an enlarged detail section of the return coin magazine and manner in which the coin is delivered therefrom.

Fig. 6 is a section of the line 66 of Fig. 4 and I Fig. 7 is a front view of the machine on a reduced scale.

As shown in the drawings the machine is provided with a casing composed of a back wall 10, sides 11 top 13 and a bottom 1% Serial No. 527,722.

which extends forwardly to support by means of a front piece 15 and an intermediate member 16, a horizontal table or shelf 17. Freely mounted for vertical movement in a suitable bracket 18 upon said table is a tubular shaft 19 having at its top a cup shaped portion 20 adapted to; have secured therein a padded ball 21. The lower part of the shaft 19 may be guided by a shaft 22 which extends upwardly into the bore of the shaft 19 and which is preferably provided at its lower end with a flanged portion adapted to be suitably secured to a cross piece 23, extending between the members 15 and 16. lhe lower end of the tubular shaft 19 rests upon the end of a pivoted lever 26%, the other end of said lever having pivoted thereto a vertically extending impact member 25 having at its upper end a suitable buffer or contact member 26 of rubber or other suitable material. A spring 27 normally urges the lever 24; in a clockwise direction (Fig. 1) to hold the ball 21 elevated and the member 26 lowered out of contact with the lower end of an indicating member 28 which may be constructed in the shape of an aeroplane. A suitable adjustable stop 24C may be provided to regulate the extent of travel of the lever 24.

The member 28 is mounted for free vertical movement on a guiding member 29 which may be a wire, string, rod or other desirable material and which is suitably secured to extend from the top 13 to the table 17. A scale plate- 30 is suitably graduated as shown in Fig. '4, the figures representing figuratively the height in feet of the upward flight of the aeroplane. If desired each set of characters may be given also the name of one of the well known powers or countries.

The tail of the aeroplane is provided with a spring pressed ratchet 31 which extends through a longitudinal slot 32 in said scale plate to engage with the teeth of a ratchet bar 33 provided with the angularly inclined slots 34 through which suitable securing means such as the screws 35 are passed. To the upper end of the ratchet bar a spring 36 is secured to normally hold the bar in its elevated forward position while the lower end of the bar is provided with a rearward extension which is adapted to contact with the periphery of a cam 38 mounted 011 a shaft 39 which is suitably journaled in the back 10 and intermediate member 16. A stop cam 40 is mounted on the shaft 39 and min! is adaptcd to'be engaged the hooked end 43 of a stop le er 41 suitably pivoted as by means of the bar 42 within the casing. The

other end of the lever 41 is directly beneath a coin chute M which passes upwardly and forwardly to connect with the, usualycoin slot 45 provided in the front of the machine. The shaft 39 connected by a suitable gear train indicated generally by the numeral 46 with a spring motor 47 adapted to be wound by anysuitable means "such as the bevel gears A spring "56 'horr'n'ally keeps the bell crank with the 52 lowered'dircctly' into the path of the aeroplane. A return coin chute 57 is 'situted with'its mouth "below the casing 54 and terminates its lower forward end in the'ret ir'ncup 58.

The pel-anal ofthe' d'evic'e is a follows:

A coin being inserted in the slot 45 travels downwardly through the chute '44 and drops upon the end 6f the p'ivote d lever 41 causing the end 4236f the *iever to be raised, re'lea'sing the stop cam '40 thereby permitting "the cam shaft 39 to rotate tinder the influence of the spring meter, thus "rotating the cam 38 which byit's rotation pi esses uownwardly against the extension of the ratchet bar 33 causes the bar to lnov'e' down'wardly "and 'rearwardiy by "means of the inclined "slots 34: and bolts '35. The ratchet bar therefore will be 'lii OV ECl tjdt of ngtt'gnieht With the ratchet pawl 31 prtijecting ffrd'm the tail oi the iiidicating member 2 8, thus "allowin'g "the member 28, which "we will "assume has been driven upwardly toth'e-dotted line position sliowh in Fig. "lfby a previous operation of the machine, to fall t'o the full line position i'n' -cdhtiict with the stdp "528 where it is in po's'ition to receiveaiiother iiiip'etu's frbm the impact member 25. The rotatin of the cain shaft is then stopped after one revolution by the "ei igag'em'eht 'of the hooked end '4 of the stop lev'er 5L1 with the" slioulder 43 etureewp cain an, the arm 38-at "th'esaihe time eccupynig the posit-inn show in Fig. 3, thus allowin the ratchet bar 33 to be 'pull'ed upwardly "and "i'or'wardly by the spring 36. The user of -the machine then delivers 'a blow'withhi's fist uponth'e padded ball 21 cz'iusing tl'ie'tubularshaft 19 toiinove thehinted lever ar-and driving-theimpaet member 25 against the bottom of the indi eating member 28, thus causing it to travel upwardly along the guide 29 with the spring pressed ratchet pawl in engagement with theratche't bar 33. The upward eX- tentof the travel of the indicating member will obviously be proportional to the force ot-the blow delivered to the ball 21 and the indicating member will be held at theupper point of its travel by the ratchet pawl.

If the indicating member is driven to the extreme u per end of the rod it will strike the horizontal arm 52 thus actuating the bell crank 50 and causing 'acoi'n to be delivered from the coin"magazine through the chute '57 to the cup 58'.

It will 'be understood that the indicating device may be made in any shape or form but I prefer to construct it in the form of ail-aeroplane and to provide the's'cale with gradua'tions the upper ones which correspond approximately to the highest altitudes attained in actual flights thereby presenting an attr'actiye incentive to use the machine.

Having thus'descr ibed my invention what I claim as new and desire to secure by Let ters Patentofthe United I States is 1. In a deviceo'f 'thechar'acte'r described, a scale plate provided with graduations, a vertically extending guide adjacent said scale plate, an indicating member movable "along said guide, a z-padded member adapted to receive a blow, means to transmit the force of said blow to the indicating. unembe'r whereby it will *be caused to travel upwardly along said guide and means "to hold "said indicating member at the upper :point of its travel comprising a ratchet :pawl a ratchet bar slidably mounted for longitudi- 'nal and lateral movement into and out of engagement with -said pawl and means to normally hold 'said ratchet bar in "engagement withsaid :pawl. 7
